The DVR®2000E+ has the following features:
• Three regulation modes: Single or three
phase Automatic Voltage Regulation (AVR) or
Field Current Regulation (FCR) modes
• Adjustable soft start in AVR mode
• Under frequency (volts/hertz) regulation
• Single or three phase generator current
(RMS) sensing (with optional CTs)
• True three-phase power metering
• Generator paralleling with reactive droop and reactive differential
compensation
• Front-panel 4-digit human-machine interface (HMI) for
configuration and monitoring
• Windows® based software for configuration and monitoring
• MODBUS protocol via RS232
• Controller Area Network (CAN) interface for metering and control
• Regulator conveniently mounted in a low voltage control section
within the conduit box to facilitate external adjustments.
Heavy-Duty Shielded Ball Bearings…are designed for a minimum B-10 life of
40,000 hours. The bearings are protected
on each side by cast-iron bearing caps to
prevent contamination from entering the
bearing. Extended grease and relief fittings
make bearing regreasing easy. As a result
of the superior single piece lamination
construction, the MAGNAPOWER® has very
low self induced shaft currents and for this
reason does not require insulated bearings.
MAGNAPOWER® generators are available in single or two bearing
construction (1020 frame).
Rotor Construction…a Marathon Electric exclusive, features single
piece rotor laminations and an ammortiseur
winding. The copper field winding is layer
wound with thermo setting epoxy for high
mechanical and electrical integrity and has
an overcoat of tropical insulation for added
environmental protection.
High Voltage Insulation System (11.0 kV – 13.8 kV Models)…utilizes advanced materials resulting in
superior performance. The turn insulation
is a calcined muscovite mica with an epoxy
resin providing excellent voltage surge
protection. The ground wall tape is an
uncalcined muscovite mica tape with low
binder content. This results in good
voltage endurance and greater tape porosity
enabling complete resin impregnation during
the VPI process. The slot section of the coil
is wrapped with a low resistance conducting tape to provide corona
protection. The coil end turns utilize a semiconductive gradient tape
and a protective tape system ensuring optimal voltage de-stressing
and superior environmental protection. The entire stator assembly
incorporates form wound coils and is vacuum pressure impregnated
(VPI) with anhydride epoxy resin, well known for its excellent
electrical and mechanical properties. Finally, an overcoat of tropical
insulation is applied for added environmental protection.
Low And Medium Voltage System…also incorporates form wound coils and VPI insulation systems.
Rugged Construction…assures low vibration and long life. Internal frame supports, external
girth rings, and rigid mounting feet are welded to the rolled steel
plate to form a strong, unitized frame.
Brushless Exciter…is mounted outboard of the bearing for ease
of inspection and maintenance. The rotating
rectifier assembly utilizes 1000 volt rectifiers
and a surge suppressor for protection from
induced voltage spikes.
Permanent Magnet Generator (PMG) Excitation System…provides 300%–60 Hz (250%–50 Hz) short
circuit excitation support for a minimum of
10 seconds and isolates the regulator power
circuit from load disturbances. The PMG is
mounted outboard of the bearing for ease
of inspection and maintenance.
Conduit Box…assembly is optimized for customer flexibility. Various access panels
and a low voltage control section are provided. The external load
leads can enter the conduit box from the top, bottom, or side.
Furthermore, the conduit box is designed to accept various auxiliary
devices (potential and current transformers, etc.) while maintaining
a compact generator outline. All models are equipped with an end-
mounted conduit box as standard.
Conduit Box Options…optional conduit box designs are available to meet customer
requirements.
DVR®2000E+ Patented PMG Powered Digital Voltage Regulator…is an encapsulated design for reliable operation in all environments. Fully tested to withstand 20g’s in all planes and vibration to 0.050 inch peak.

The DVR®2000E+ has the following features:
• Three regulation modes: Single or three
phase Automatic Voltage Regulation (AVR) or
Field Current Regulation (FCR) modes
• Adjustable soft start in AVR mode
• Under frequency (volts/hertz) regulation
• Single or three phase generator current
(RMS) sensing (with optional CTs)
• True three-phase power metering
• Generator paralleling with reactive droop and reactive differential
compensation
• Front-panel 4-digit human-machine interface (HMI) for
configuration and monitoring
• Windows® based software for configuration and monitoring
• MODBUS protocol via RS232
• Controller Area Network (CAN) interface for metering and control
• Regulator conveniently mounted in a low voltage control section
within the conduit box to facilitate external adjustments.
Heavy-Duty Shielded Ball Bearings…are designed for a minimum B-10 life of
40,000 hours. The bearings are protected
on each side by cast-iron bearing caps to
prevent contamination from entering the
bearing. Extended grease and relief fittings
make bearing regreasing easy. As a result
of the superior single piece lamination
construction, the MAGNAPOWER® has very
low self induced shaft currents and for this
reason does not require insulated bearings.
MAGNAPOWER® generators are available in single or two bearing
construction (1020 frame).
Rotor Construction…a Marathon Electric exclusive, features single
piece rotor laminations and an ammortiseur
winding. The copper field winding is layer
wound with thermo setting epoxy for high
mechanical and electrical integrity and has
an overcoat of tropical insulation for added
environmental protection.
High Voltage Insulation System (11.0 kV – 13.8 kV Models)…utilizes advanced materials resulting in
superior performance. The turn insulation
is a calcined muscovite mica with an epoxy
resin providing excellent voltage surge
protection. The ground wall tape is an
uncalcined muscovite mica tape with low
binder content. This results in good
voltage endurance and greater tape porosity
enabling complete resin impregnation during
the VPI process. The slot section of the coil
is wrapped with a low resistance conducting tape to provide corona
protection. The coil end turns utilize a semiconductive gradient tape
and a protective tape system ensuring optimal voltage de-stressing
and superior environmental protection. The entire stator assembly
incorporates form wound coils and is vacuum pressure impregnated
(VPI) with anhydride epoxy resin, well known for its excellent
electrical and mechanical properties. Finally, an overcoat of tropical
insulation is applied for added environmental protection.
Low And Medium Voltage System…also incorporates form wound coils and VPI insulation systems.
Rugged Construction…assures low vibration and long life. Internal frame supports, external
girth rings, and rigid mounting feet are welded to the rolled steel
plate to form a strong, unitized frame.
Brushless Exciter…is mounted outboard of the bearing for ease
of inspection and maintenance. The rotating
rectifier assembly utilizes 1000 volt rectifiers
and a surge suppressor for protection from
induced voltage spikes.
Permanent Magnet Generator (PMG) Excitation System…provides 300% short
circuit excitation support for a minimum of
10 seconds and isolates the regulator power
circuit from load disturbances. The PMG is
mounted outboard of the bearing for ease
of inspection and maintenance.
Conduit Box…assembly is optimized for customer flexibility. Various access panels
and a low voltage control section are provided. The external load
leads can enter the conduit box from the top, bottom, or side.
Furthermore, the conduit box is designed to accept various auxiliary
devices (potential and current transformers, etc.) while maintaining
a compact generator outline. All models are equipped with an end-
mounted conduit box as standard.
Conduit Box Options…optional conduit box designs are available to meet customer
requirements.
DVR®2000E+ Patented PMG Powered Digital Voltage Regulator…is an encapsulated design for reliable operation in all environments. Fully tested to withstand 20g’s in all planes and vibration to 0.050 inch peak.
